What exactly one mean when they say "stood standing" in a sentence?
"Mr. rumbold, I have a complaint, and I am unanimous in this! We've been stood, standing, waiting downstairs for that lift, and it wasn't working..."
"Oh, I'm worn out to start with. I have stood standing in the bus all the way
"We have been sat, sitting here for half an hour and nothing arrived, except you"
Is this phrase grammatically correct, or might it just be a script error? Can you please explain when this type of emphasis can be used, and if it's commonly being used?
